Migrate bootlimit to Kconfig

Migrate boards which set bootlimit in the environment to Kconfig.

We exclude gurnard_defconfig which includes a bootlimit=, but doesn't set
CONFIG_BOOTCOUNT_LIMIT, so we'd fail to include a bootlimit setting
if we migrated it.

display5_defconfig and display5_factory_defconfig share a SYS_CONFIG_NAME,
but only display5_defconfig enables CONFIG_BOOTCOUNT_LIMIT, so we fail to
set bootlimit= in display5_factory_defconfig. This is okay because the
display5_factory_defconfig doesn't need to have it set, as it is only
meant to prepare the board in the factory.

Environment changes for all modified configs as seen from buildman:

  boards.cfg is up to date. Nothing to do.
